Sen. Kirsten Gillibrand wrote on Facebook that while Franken is entitled to have the Ethics Committee conclude its review, “I believe it would be better for our country if he sent a clear message that any kind of mistreatment of women in our society isn’t acceptable by stepping aside to let someone else serve.”

Sens. Mazie Hirono of Hawaii, Maggie Hassan of New Hampshire, Patty Murray of Washington state and McCaskill joined Gillibrand in pressing for Franken to quit.
